Atopic dermatitis is a chronic inflammatory and recurrent dermatosis, the frequency of which increases regularly in industrialised countries. It begins in the first months of life and the clinical presentation changes with the age of the child. The diagnostic is clinical in the majority of cases. Sometimes allergological explorations are necessary. The treatment has two objectives: treatment of the flares (mainly topical corticosteroids) and preventive adjuvant measures. The use of topical immunosuppressors reinforces the therapeutic management, after failure of topical corticosteroids.
